CHURN-MOTOR.

SPECIFICATION forming part of Letters-Patent No. 300,620, dated June 17,1884-.

Application filed April 25, 1884. (No model.)

To all whom it may concern:

- Be it known that I, JOSEPH L. MOKAY, a citizen of the United States,residing at Neoga, in the county of Cumberland and State of Illinois,have invented certain new and useful Improvements in Churn-Motors; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to that class of churnmotors which employ aspring-power mechanism acting upon the dashers.

The object of my improvements is to provide a simple and improved motorwhich will possess advantages in point of ease of operation and generalefficiency, and which can be governed and adjusted-with superiorconvenience and facility.

In the drawings, Figure 1 is a perspective view showing my improvedmotor in position upon the churn. Fig. 2 is a side elevation thereof,the side of the casing being removed and parts of the interior framebeing broken away to show the construction. Fig. 3 is an end view of thesame, part of the casing being removed. Fig. 4. is a detail side view ofthe balance-wheel mechanism. Fig. 5 is a detail sectional view takenthrough the balancewheel mechanism. Fig. 6 is adetail side view showingthe retainingspring of the lock or stop mechanism. Fig. 7 is a detailperspective view of the top or cover of the churn, the motor-casingbeing removed. Fig. Sis a vertical transverse sectional view in detail,taken through the standard and the top or cover to which it is secured.Fig. 9 is ahorizontal detail sectional view'taken 011 the line a: m,Fig. 8. Fig. 10 is a detail sectional view illustrating the means forsecuring the motor-casing in position on the top of the churn.

Corresponding parts in all the figures are denoted by the same lettersof reference.

Referring to the drawings, A designates the top or cover of a churn,which is fitted to the body of the churn (shown in dotted lines) in anydesired manner, and may be of any suitable construction. A perpendicularstandard is provided upon the top A, and is preferably its side and topedges, as shown.

formed by two parallel standards, B B, having bearings at their top fora transverse shaft, 0, carrying a gear-wheel, D, arranged between thesaid standards. Each standard B is provided with a vertical guide-slot,b, in whichworks an approximately H shaped sliding head, E,havingalateral projection, e, in which one of the da'sher-staffs isvertically adjustable by means of a set-screw, F. The shaft 0 isprovided with oppositely-cranked endsc c, from which extend rods orpitmen G G, which are pivotally connected at their lower ends to theheads B. By this arrangement the rotation of the shaft 0 causes theheads E to reciprocate vertically and in opposite directions, thusimparting a reciprocating motion to the churn-dashers. A perforation, a,is provided in the top A at each side the standard, through which thedasher-staffs work, the staffs being designated by the letter H.

I designates the casing which contains the motor mechanism, andcomprises an interior frame, J, to which the casing is secured. Thiscasing J comprises side pieces, j j, forming bearings for the motormechanism, and provided with inwardly-proj ecting flanges j at The sidepieces or boards, 1' i, of the/casing proper are secured to the sides jj of the interior frame by means ofscrews, or in. any other suitablemanner. The ends and top of the casing are preferably formed by a singlebent strip, '6, which is secured to the inwardly-projecting flanges j inany suitable manner. Openings 2' are preferably provided at the bottomof the sides i, through which the-motor mechanism may be convenientlyinspected.

Transverse flanges K K project from the bottom of the interior frame, J,at each end of the casing, by means of which the latter is secured inposition upon the churn top or cover. At one side of the top A isprovided a plate, L, having a lip, Z, under which one of the flanges Kis adapted to be adjusted, and upon the opposite side of the top A aplate, M, is adapted to be adjusted over the other flange K, to lock thecasing in position. This plate M is provided with end slots, at m,whichreceive guide-pins n12, projecting from a baseplate, N, secured upon thetop A, and the said plate M is also provided with a projecting lug, m,by which it may be operated.

A suitable spring-motor mechanism similar to that used in clocks orother devices is pro-' vided within the casing, this mechanism beingadapted to be wound up by a suitable key, and embodying a train ofgear-wheels, the lower one of which, 0, is adapted to mesh with the gearD when the casing is secured in position on the top A and over theupright standard. By this arrangemen t, when the casing is secured inposition and the spring mechanism is wound up, the motor mechanism willtrans: mit a rotary motion to the shaft 0, and the churn-dashers will bereciprocated vertically, as before specified. The speed of the motormechanism is governed by turning a pin, 1?, which projects through anopening, i in one side of the casing, and is provided with an in dicatoror finger, 1;, moving over the face of the casing. The inner end of thispin 1 is provided with an angular arm, p, whicln engages thebalance-spring Q, and serves to reg ulate the same. A spring-plate, It,is interposed between the arm 19 and the inner face of the casing J, andserves by its tension to retain the regulating-pin in the position towhich it has been adjusted. The shaft S of the balance-wheel has itsbearings in the ends of set-screws T T, working through the sides of thecasing J. The head of one of these screws preferably projects through aperforation, 6', in the side of the casing, while the head of the otherscrew projects through the perforation i" at the other side, by whicharrangement the screws may be conveniently adjusted to regulate thebearing of the balancewheel shaft.

U designates a transverse angular rod, which has its bearings in theframe J, and is pro vided with a head, a, projecting through aperforation, a", in the side of the casing. By simply turning this headthe rod U is brought into engagement with the teeth of the gearwhecl 0when desired to stop the operation of the motor. By turning the head inan opposite direction the stop mechanism is disengaged from the teeth ofthe gear 0, and the mechanism will automatically resume its operation. Aspring-plate, V, is interposed be tween the crank of the rod U and theinner face of the casing J, and serves by its tension to retain the stop-rod in any condition to which it is adjusted.

Suitable bails or handles, V W, are provided upon the ends of thecasing, by which the motor mechanism may be conveniently lifted from thetop of the churn after the operation of churning has been effected.

From the foregoing description and annexed drawings the operation andadvantages of my invention will be readily understood.

The motor mechanism can be readily and conveniently connected with ordisengaged from the churn, and its speed is easily regulated andgoverned while it is in position and during its operation. The casinghas simply to be applied to the churn top or cover and fastened inposition, when the mechanism is wound up, and will then automaticallyeffecta quick and thorough churning.
